PROBLEM TO BE SOLVED: To make a circuit scale and a wiring quantity less than in the conventional case. SOLUTION: The register readout circuit of the prevent invention is given X successive selected register numbers at the same time and read corresponding register values out at the same time. The circuit has register value selecting means by residues which each select one value out of the values of all registers having register numbers of the same residue of division by X according to a given selection control input, a selected register number exchange means which allocates the respective selected register numbers as the selection control input to the register selecting means for residues equal to the residues obtained by dividing the selected register numbers by X, and X output selection means which select and output values corresponding to the corresponding selected register numbers among the values outputted by all the register value selecting means and output them. To a microprocessor as an embodiment, this register readout circuit is applied.
